Protests broke out in St. Louis after former police officer Jason Stockley was acquitted Friday of first-degree murder in the 2011 shooting death of black driver Anthony Lamar Smith.
At least 23 people were arrested and 10 law enforcement officers injured in protests Friday night.
Protests started peacefully with some people making their way to the police headquarters to call for officers’ resignations. St. Louis police said the demonstrators later threw rocks at the mayor’s home and hit officers with water bottles.
St. Louis Metro Police Department Chief Lawrence O’Toole said his officers showed great restraint despite injuries.
Video footage showed officers using tear gas to disperse the crowds after police said the protests were considered an unlawful assembly. O’Toole said his officers used pepperballs.
